Electricity prices

Horizon Power delivers energy solutions to regional and remote Western Australia and is focused on ensuring reliable electricity is provided to our customers in the most efficient way to reduce costs.

Each year, the WA State Government reviews Horizon Power’s tariffs, fees and charges, and sets the price that customers pay for electricity. These changes better reflect the cost of generating electricity, maintaining the electricity grid, providing customer services and providing safe, reliable electricity to regional WA. This annual review determines the regulated electricity tariff, fees and charges to apply to all customers throughout Western Australia under the WA State Government’s Uniform Tariff Policy.

The WA State Government subsidises the price of electricity as it costs more to deliver power to customers in regional and remote Western Australia than the price that customers are actually charged. In 2020-21, the subsidy will be $185 million for regional electricity, or $3,972 per customer connection for 2020-21.

The A2 tariff is the standard residential tariff applied to private dwellings (houses, home units, flats, apartments) used solely for residential purposes. It offers customers the same flat rate energy charge regardless of where they live and which time of the day electricity is used.

Supply charge $1.0514 /day
Supply charge: additional homes $0.4180 /day
Variable charge 29.3273 c/kWh

NWIS/Regional Caravan Parks

The State Government recognises that caravan parks in the North West Interconnected System (from Karratha to Port Hedland) and regional off-grid power systems may be disadvantaged if they are paying business tariffs higher than the residential tariff. As a result, Horizon Power has developed the Caravan Park Tariff Compensation Program. 

Please see below for more information about how the Scheme will affect you.
